But I have no idea how to cross-compile it with GCC runtime, do you have any document for it or could you show me a brief instruction.

FYI, You can build it with 
`clang --target=m68k $(SOURCE_FILE) -c -o` 
and then
`m68k-linux-gnu-gcc $(SOURCE_OBJECT) -o $(FILE_NAME)`

or
`clang --target=m68k $(SOURCE_FILE) -o $(FILE_NAME) -ccc-gcc-name linux-gnu-gcc`
